It is not uncommon for blood pressure to take time to stabilize after a hospitalization. Your reading of 160/120 mmHg suggests your current regimen of telmisartan, aspirin, and prazosin needs adjustment, as individual responses to blood pressure medications vary. Please contact your prescribing doctor or cardiologist promptly. They may need to safely increase your dosage or add a complementary medication to bring your numbers down. Do not alter your medication doses on your own. However, if you experience chest pain, shortness of breath, or a severe headache, please seek immediate emergency medical evaluation.
